摘　　要：开展雷电电磁环境的研究需要1台2ms的方波冲击电流发生器.文章从基本的LC回路出发,利用Multisim电路仿真软件,重点研究了L型链路参数对方波冲击电流波形的影响,总结了电流峰值、峰值持续时间与充电电压、链路数量、电感及其内阻、电容器和负载电阻等电路参数的关系,并设计了满足国家标准要求的方波电流发生器装置.实验结果显示,测试波形与仿真分析较为吻合,该设计方法可以为方波发生器(包括电压发生器)的设计提供理论基础.In order to study the electromagnetic environment of lightning,a 2 ms rectangular pulse current generator is needed.Based on the LC circuit,the influence of loop parameters on rectangular pulse current waveform is studied by using Multisim software.The relationship between peak current,peak duration time and circuit parameters such as charging voltage,the number of links,inductor and its internal resistance,capacitor and load resistor are summarized.At the same time,a rectangular pulse current generator is designed to meet the standard requirements.The experimental results show that the waveform is in good agreement with the simulation analysis.The design method can provide theoretical basis for the design of rectangular wave generator(including voltage generator).
